• Lug Type
  Threaded inserts on both sides allow the valve to be installed in dead-end service.

• Double Offset (High-Performance)
  Improved sealing and reduced wear, suitable for higher pressure and temperature ranges.

• Triple Offset (Zero Leakage)
  Metal-to-metal seated valves designed for critical applications with high cycle life and zero leakage.

• PTFE-Lined Butterfly Valves
  Ideal for corrosive chemical applications due to excellent chemical resistance.
  
  

Applications
